LM1117MPX-25NOPB

onsemi · Linear Voltage Regulators (LDO) · SOT-223

LM1117MPX-25NOPB from onsemi, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Adjust/Ground power_in On this fixed 2.5 V part pin 1 is the ground terminal, and the datasheet states the fixed-output ground current ranges from 3.0 mA to 5.0 mA depending on output voltage.
2 Output power_out Regulated 2.5 V output rated for up to 800 mA load current, with the heatsink tab electrically connected to this pin and output current limit of 1000 mA to 2200 mA.
3 Input power_in Unregulated supply input with a maximum input voltage of 20 V, and the 2.5 V version is specified for regulation with Vin from 3.9 V to 10 V.
